Improvement in sash-holders



PATENT o AARON TIEIOMAS, OF MILTON, ILLINOIS.

IMPROVEMENT IN SASH-HOLDERS.

Specification forming part of Letters Patent No. 122,743, dated January 16, 1872.

To all 'whom it may concern:

Be it known that I, AARON THOMAS, of Milton, in the county of Pike and State of Illinois, have invented a new and valuable Improvement in Window-Fasteners; and I do hereby declare that the following is a full, clear, and exact description ofthe construction and operation of the same, reference being had to the annexed drawing making a part of this specicatiOn, and to the letters and figures of reference marked thereon. y

Figure l of the drawing is a representation of a side View of my fastener. Fig. 2 is aside View. Fig. 3 is a view showing its application to the jamb of a window.

My invention relates to meansv for holding and operating a window-sash; and it consists in the construction and novel arrangement of devices by means of' which the sash can be fastened or supported at any desired height within the limit of play while the fastening devices will not interfere with the free play of the sash.

In order to enable others skilled inthe art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation. Y

, In the accompanying drawing illustratin my invention, A represents a metallic plate, which is attached to the side of a sash-frame by means of screws. B represents atapering recess in the rear face of the plate for the adjustment of the roller D, hereinafter mentioned.

, The roller D plays loosely in said recess, and

is arranged to move up and down therein. This recess formed in the plate A is open to ward the jamb, and through this open side the roller comes in contact with the jamb when it is raised. The lower end of the tapering recess B is expanded to forni a circular pocket, H, for the reception of the roller Ywhen down. The circular expansion intersects the wall E, a portion of it extending behind ihe-prolongation of this Wall in such a manner that when the roller is in the pocket its edge will not be in contact with the jamb. The diagonal wall is corrugated, so as to assist in securing and wedging the roller against the sash to keep the sarnet'rom dropping. The circle H is a receptacle for the roller D and the roller remains in the position shown in Fig. l, until it is raised or operated by the projecting rodz at the bottom of the plate A, bringing it in contact with the jamb. When the sash is raised to the desired altitude the roller D is pressed upward by the projecting rod or keyz against the window-jamb, and the weight of the sash falls upon the roller, pressing it against the corrugated shoulder or inclined w all E, thereby holding said sash in place at this point.

I claim as my invention- The window-sash, provided with the fastener described, consisting of the plate A, having the upwardly-tapering recess B., with circularl pocket H at its lower end, roller C, and vertically-sliding key z, all constructed and arranged to operate as specitied.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

AARON THOMAS.
